Software Developer · Chennai, India

Hi, I'm Geoffrey.

I design and build production software from interface to infrastructure.

Web interfaces in Next.js and React, mobile apps in React Native and native Swift, and the Express, PostgreSQL, Redis, and AWS layers that keep them running. Lately I've been going deep on Swift and SwiftUI by building an iOS app from the ground up.Building high-performance web applications in Next.js, native iOS products with Swift & SwiftUI, and cloud architectures on AWS.
